For the first time, scientists have found direct evidence of the expansion of the universe, a previously theoretical event that took place a fraction of a second after the Big Bang explosion nearly 14 billion years ago.
Scientists found and measured a key polarization, or orientation, of the microwaves caused by gravitational waves, which are miniature ripples in the fabric of space.
In addition to providing the first direct evidence of the universe’s inflation, the measurements can be used to date the process and determine how much energy it took.
“This is not something that’s just a home run, but a grand slam. It’s the smoking gun for inflation. It hints at unification of the fundamental forces at energies 10 trillions of times higher than those accessible at the Large Hadron Collider at CERN,” Kamionkowski said.
Of course the proper scientific attitude is ...
“These results are as extraordinary as they get, and they will require the most extraordinary scrutiny,” Kamionkowski said.
